Bolts have a head on one end this is generally a hex head and are threaded on the other.

Bolts and screws can both give a secure hold in fastening operations. still, these fasteners aren't the same. generally tone- tapping, a screw features a spiral groove wrapped around a shaft. The vestments of the screw mate with the material it's turned through to hold the screw in place. Screws nuts and bolts, on the other hand, aren't tone- tapping and bear a nut to stay secure.
